The average of −8 and 7 according to my online hw thingy 1/2 is incorrecto

v: l•w•h÷2.

v: 20•6•8 ÷2

v: 960÷2

v: 480

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
